Y.,-A ,conronarron or new YORK I This invention relates to new and useful improvements in 1gmt1n composltions, and

has for its object the providing of an igniting composition particularly adapted for use in connection with fuse bands capable of use in the making of self-lighting'cigarettes, cigars and little cigars. It is also capable of many other uses.

The invention consists in the novel compositions hereinafter described'and claimed, but it is not intended that the invention be limited to the particular preferred form set forth, but the scope of the invention is as set forth infthe claims.

We have found that if, in the manufacture of igniting compositions, a substance such as nitrocellulose is used, a composition is formed peculiarly adapted for use in connection with self-lighting cigarettes and with fuse bands adapted to be attached to the ends of such cigarettes. A preferred form of making an ordinary strike-anywhere igniting composition embodying our invention is as follows:

Four parts of potassium chlorate or other suitable oxidizer in proper proportion, one part of sulphur, three parts of a frictionizer such as ground glass, and one-half part of a substance such as red phosphorus are thoroughly mixed together in dry form. Two parts of the powder are then mixed with one part'of nitrocellulose dispersion or solution of a consistency of 12 ounces of nitrocellulose to a gallonof the solution in a dispersing agent such as benzol and ethyl acetate. The resulting mixture may be. then spread on a previously-prepared fuse band, and, as the 1powdered y spread oversuch surface, being bound by the nitrocellulose, and will serve as an igniting composition for same when rubbed against any abrasive surface.-

This form of igniting composition is particularly adapted for use with a fuse composition described in an application filed on even date herewith In lieu of spreading the igniting composition on top of a previously-prepared fuse composition, the fuse compgsition and the igsiting composition may mixed together renrrms comrosrrron Application filed September 5, 1925. Serial No. 54,796.

and a single spread made of both the fuse composition and the igniting composition.

Whether the igniting composition be spread on the fuse composition or be mixed with same' an advantageous combination'will result, inasmuch as both the fuse composistituted for the nitrocellulose with somewhat similar results, as same are combustible and self-oxidizing or are provided with an oxidizing agent. I

.A safety form of igniting composition may be made in accordance with our invention by mixing together potassium chlorate eighteen parts, manganese dioxide and iron peroxide two parts each, bichromate of potash one and seven-tenths parts, sulphur powder one part, and ound glass four parts. After same have n thoroughly mixed in dry form," the powder is mixed in ten parts with seven parts of nitrocellulose solution of a consistenc of that previously described, and'five agent'as ad itional parts of a dispersin ethyl acetate are added thereto. ese lngredients are throughl mixed in a receptacle,

allowed to stand an drawn from the bottom and spread over a fuse band forming a thin lamination thereon, or may be mixed in with the fuse composition before spreading, or may be used in other wa s. Here again the usual comminuted ingre ieuts of safety igniting compositions have been mixed and held by a plastic binder'which is self-combustible or of the strike-anywhere igniting composition. T00

"'65 mixed with an oxidizing influence, and the ingredients in such substances,

The i ting composition willi 'te on an commog s afety match striking ssi i' asive. striking surface for the igniting composition, however, may be composed of a frictionizer of twelve parts of lass powder mixed with five parts of red phosphorus, and cemented with four parts of nitrocelluose solution of a consistency previously described. The mixture is thinned with ethyl acetate for suitable spreading, and may, if desired, be darkened with lamp black, red' oxide or other coloring matter. The use of a substance such as nitrocellulose in the abrasive surface renders same moisture proof and, being itself combustible andself-oxidizing, likewise aids in the ignition of the igniting composition by more freely liberating the sparkon striking. In-

stead of retardin ignition as dothe ordinary glues used as bin ers, the nitrocellulose binder itself enerates heat at the friction point. This ena%1es the igniting composition to be ignited with less friction.

The nitrocellulose as used in the igniting compositions and in the striking surface described not only serves as a binder for the but, being itself a transporter of combustion and selfcombustible, it effectively aids inthe proper action of the igniting compositions. It. is

also plasticand renders the mixtures flexible and capableo'f being manipulated into ribbon formf It also renders the mixtures moistureroo a What we claim as new and desire to secure by United States Letters Patent is v 1 A safety igniting composition for selflighting cigarettes, cigars and the like consisting of potassium chlorate, manganese dioxide, iron peroxide, potassium bichromate and sulphur, agglutinated with a nitro-cellulose substance into a plastic compound.

2. A safety igniting composition for selfcigars or the like consisting of ten parts of powder formed from eighteen parts of potassium chlorate, two parts of manganese dioxide and iron oxide each, one and seven-tenths parts of potassium bichromate, one part of'sulphur and four parts of ground glass; and seven parts of nitro-cellulose dispersion 'of consistency of substantially twelve ounces of nitro-cellulose to a gallon of dispersing agent;

In testimony whereof, we have signed our names tov this specification.
